Abstract

A device for pivotally mounting an object on a support such that the object can be set in a desired angular position, comprises a base adapted to be mounted on the support and having a dish-shaped recess, a ball received in the recess and having a spacer bolt projecting therefrom for attachment to the object, a nut for forcibly urging the ball into the recess to clamp the ball in a desired angular position, and a plurality of protuberance in the dish-shaped recess. The ball is made of a material sufficiently soft relative to said base to permit the protuberances to penetrate the ball by deformation of the surface thereof and thereby lock the ball in the desired position.

Description

~ 3 The present invention relates to mounting devices, and more par-ticularly to a device for pivotally mountiny an object on a support such that the object can be set in a desired angular position.

Mounting devices of this kind are known which comprise a base adapted to be mounted on the support and having a dish-shaped recess receiving a ball connected to a spacer bolt for attachment to the object. The dish-shaped recess is surrounded by a threaded collar on which is mounted an lo attachment nut that is placed around the spacer bolt and screwed firmly to the collar to clamp the ball in a desired set angular position. The attachment nut has an inwardly projecting edge with a dish-shaped chamfer~ The spacer bolt is connected to an attachment plate intended to be fastened to the object.

In such devices, it is necessary to screw down the nut very tightly in order to achieve a stable locking of the object, that is in order to ensure that the object will not move out of its set position. Another drawback with these devices is the risk that they will become permanently locked in one set position due to the fact that the ball has become clamped or pinched in the lower part of the attachment assembly, partly as a result of the larye clampiny force appl;.ed to the nut and partly because of the unsuitable confiyuration of the dish-shaped recess. '!

An object o~ the invention is to alleviate the drawbacks associated with known pivotal mounting devices means and to provide a pivotal mounting device whi~h can be readily adjusted to different angular positions and setting positions and with which the risk of the ball being locked permanently in the recess is minimized.

According to the present invention there is provided a -device for pivotally moun-ting an object on a support such that the object can be set in a desired anyuLar position, comprisiny a base adapted to be moun-ted on the support and having a dish-shaped recess, a ball received in said recess and having means projecting therefrom for attachment to the object, means for forcibly urginy said ball into said recess to clamp said ball in a desired angular position, and a plurality oE protuberance in said dish-shaped recess, and said ball beiny made of a material sufficien-tly soft relative to said base to perm;t said protuberances to penetra-te said ball by deformation oE the surface thereof and thereby lock said ball in -the desired position.

The protuberance are preferably in the form of wedge-shaped projections against which the ball rests. The ball is also preferably made from a material that is significantly inelastic to provide a rigid mounting for the objeGt in the set position.

The ball or spherical body is preferably manufactured from a polyester elastomer.

The urging means is preferably in the Eorm O:e an attachment nut mounted on a collar surrounding the dish-shaped recess and advantageously provided with xadially projecting arms that serve as a handgrlp.

The pivotal mounting device has several advan- tages.
One advantage is that the clamping means need not be tightened with unreasonable force while nevertheless providing a sufficiently stable attachment without disturbing the setting of the object.

Because the ball or spherical body is made of relatively soft material, the protuberances will penetrate the surface by deformation to lock the ball in position. Another ~62~

~d~an-ta~e is tha-t there is a reduced risk of the spherical body wedginy in the recess, therewith enabliny the set position of the object -to be readily changed~

The advantage afforded by manufacturing the spherical body from a polyester elastomer is that this material is sufficiently soft to enable the spherical body to be affixed over the wedges and is, at the same time, so hard that the spherical body need not be elastic, which affords stable attachment of the object without of swingingO

Because the nut i.s provided with outwardly projecting arn.s which fwlction as a handgrip, the nut can be readily tightened by hand, without requiring tools therefor.

The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings in which:

Figure 1 is a perspective, exploded view oE the components of a pivotal mounting device according to the invention; and Figure 2 is a sectional view of the pivotal attachment shown in Figure 1 when assembled.

Figure 1 is a perspective view of the components of an inventive pivotal attachment means. The attachment comprises a lower part or base 1 which is intended to be secured to a supporting surface, for instance by means of screws which pass through screw holes 2, and an upper part 3 which includes an attachment plate 4, a spacer bolt 5, an attachment nut 6 and a spherical body or ball 7. The attachment plate 4 is intended to be secured to an object in some suitable manner, for instance with the aid of screws passing through screw holes 8~

, . : :~ :

2 l~ ~9 The lower part or base includes an ou-twardly projecting or upstanding part g which has a central dish-shaped recess lQ. The outer surface of -the projecting part 9 has formed thereon an external scre~ thread ll for eng~gement with a corresponding screw thread on the nut 6. The radius of the recess 10 is somewhat larger than the radius of the spherical body 7 and is provided with vertically extending wedge-shaped projections 12, which lie against the spherical body.

The spacer bolt 5 is moulded in the attachment plate 4 so that it cannot be twisted relative to the plate, or is attached to said plate in some other suitable manner. The outer end of the spacer bolt has an hexagonal configuration, or some other non-circular configuration, and is attached to the spherical body 7 .in a corresponding cavity 13 therein 1~ with the aid of a screw 14 accommodated in a recessed hole 15 in the spherical body, as clearly shown in Figure 2. The nut 6 is passed over the bolt 5, prior to secur.ing the spherical body 7 on said bolt. The nut 6 is provided with an edge 16 which projects out over the spherical body and which is provided with a dish-shaped chamfer or bevel 17 which lies against the spherical body and holds said body firm. The n~lt is also provided with radially and outwardly projecting arms 18 which function as a hand grip when tightening and loosening the nut.

When the nut 6 is tightened against the lower part 1, the edge 16 presses the spherical body 7 into abutment with the projections 12 in the recess 9 of the lower attachment part, thereby causing the projections to penetrate into the spherical body by deformation of the surface thereof to ensure positive locking of said body in an adjusted position, as illustrated in Figure 2. The wedge~shaped projections also function to ensure that the spherical body will not fasten in the lower attachment part, thereby enabling the pivotal attachment to be readily loosened in order to change ~3~2fl~

the settiny of said ob~ect.

In order to achieve positive settings, the spherical body 7 is made from a material which is softer than the material from which the lower attachment part 1 and the attachment nut 6 are made, for instance, of a polyester elastomer, which is sufficiently soft to permit the projections to penetrate into the spherical body but, at the same time, sufficiently rigid to ensure that the pivotal attachment will not swing when load is applied. The lower attachment part and the attachment nut are preferably made of a polyamide material, which is sufficiently hard to provide satis~actory strength to the pivotal attachment.

It will be understood that the invention is not restricted to the aforedescribed and illustrated embodiment and that modifications can be made within the scope of the accompanying claims.
